I am a mechanical design engineer and was wondering what is the maximum distance a fire door can be undercut by. I have contacted building control and have been informed that this is 4mm, but have been told by other engineers that they have previously been told that it is 20mm. Please could you confirm the actual dimension as i do not seem to be able to find anything with the Building Regulations either.
